The killing of the leading Iranian nuclear scientist Moshen Fakhrizadeh on Friday was as much a warning message for the incoming Biden administration in Washington as a hit against the Islamic Republic of Iran. Coincidence or not, the attack came just a few days between the most public of clandestine meetings between Israel’s prime minister Benjamin Netanyahu, the outgoing US secretary of state, Mike Pompeo and Crown Prince Mohammed bin Salman of Saudi Arabia. The prince had invited the Israeli leader and Pompeo to Neom on the Red Sea.
